Mirjana Djoric and Masafumi Okumura are widely published in the field of differential geometry. They have each contributed chapters Springer publictations and have co-published 5 papers on the topic of CR submanifolds in Springer Journals.

From the reviews: "This book contains a thorough treatment of a particular class of submanifolds, namely CR submanifolds. ... This well written monograph is aimed at researchers who are interested in geometry of complex manifolds and their submanifolds and at graduate students majoring in differential geometry. The material is to a large extent self contained ... . The authors explain in detail techniques which are relevant for this subject and provide motivation for many problems discussed in the book." (Jurgen Berndt, Mathematical Reviews, Issue 2010 h)
